A report to the West Coast Regional Council resource management committee last week said three types of errors had been identified in the maps outlining sites and areas of significance to Maori, developed for the Te Tai o Poutini Plan (TTPP):
— Ellipsoid shapes in Poutini Ngai Tahu's mapping had been transferred into "an oval" in the TTPP map.
— Areas which were to apply to water bodies only, when being plotted on to a GIS system, did not allow for the water body to have moved.
— Silent files were shown in the hard copy maps but not the online versions.
Acting planning and science manager Rachel Vaughan in her report said letters had been drafted to advise affected property owners.
"Letters have also been drafted to let property owners know that they have been incorrectly identified as having a site of significance to Maori on their property," she said.
Extracting the affected rating addresses, mail merging and customising letters had required "careful, precise work".
